I've recently switched from Chrome to Firefox in order to get extensions in Android.

However all my passwords were saved in Chrome and it would be a hassle to type in every password in Firefox again.

That's why I've found a way to transfer all your passwords from Chrome to Firefox:

1. Go to chrome://settings-frame/passwords (in Chrome)
2. Click show password on the first entry and enter your user password
3. Open the console (F12 -> top right console)
4. Copy the following code into the console and then press enter: http://justpaste.it/chrometofirefox
5. Copy the resulting page to a new txt file, save it and then rename the file to (...).clv
6. Download this extension https://addons.mozilla.org/en-Us/firefox/addon/password-exporter/ (in Firefox)
7. Press "import passwords" and then choose your CLV file.

That's it, worked just fine for me.

You can also seamlessly switch from Firefox 32bit to 64bit without loosing any data/profile.

Just install 64bit as a second install, it will automatically install to Program Files (instead of x86) and it will import your default profile from 32bit. After that, just deinstall the 32bit version.
